Review: Excellent Presence Sensor for Smart Homes - I installed the Lafaer LWR01 at the top of the stairs in my two-story home, pointing downward, as shown on my pictures… and it has been working incredibly well. It reliably detects anyone going up or down the stairs, even when they move quietly. For this use case, it’s been close to perfect. The sensor is highly configurable. You can define how long presence detection remains active, adjust sensitivity, set detection ranges, and even choose when it should trigger. I especially like that it can be configured to activate only in darkness, during specific hours, or within a defined distance. It also includes a performance mode, which adds even more flexibility depending on your needs. Integration with my smart home has been flawless. My entire home runs on the Apple ecosystem, and the LWR01 integrates perfectly with it. I can’t speak to how it behaves without at least one HomePod acting as a Thread/Matter hub, but in my setup it works seamlessly. Notifications reach all my devices instantly Apple Watch, iPhone, iPad, Mac, and even HomePod so no matter what I’m doing, I never miss an alert. Installation and setup were extremely simple. The fact that it runs on batteries makes it incredibly practical, since I can install it almost anywhere without worrying about power outlets. As long as the sensor has a good connection to the nearest HomePod (which isn’t an issue in my case), placement is very flexible. Overall, this sensor exceeded my expectations. Between its accuracy, configurability, battery power, and rock-solid Apple Home integration, it has become one of my favorite smart home devices. I liked it so much that I plan to buy additional units to cover other areas of my home. Highly recommended.
Review: Needs thread border router. - Cannot be installed without a thread border router on your network, otherwise, it seems fine.

## Questions & Answers

**Q: How does the LWR01 differ from traditional motion sensors?**
A: The LWR01 uses mmWave Radar Technology to detect both movement and stillness (e.g., sitting still, reading), ensuring true human presence detection up to 3.5m. Traditional motion sensors only react to motion.

**Q: Does it work with non-Matter ecosystem? What are the compatible smart home hub?**
A: No, it requires a Matter hub with Thread Border Router, such as Apple TV 4K (3rd gen 128GB), Echo (4th gen), Nest Hub (2nd gen), SmartThings Hub v3, or Home Assistant Yellow. Contact our CS to verify support for unlisted devices.

**Q: How do I adjust the brightness sensitivity threshold that triggers my smart lights?**
A: You can easily adjust this via the Lafaer Tool App, allowing you to set the brightness level required for your smart lights to turn on/off. Note: Smart lights and a smart home hub are required for automation.

**Q: Where should I install the sensor for optimal performance?**
A: Mount 1.5-2m (4.9-6.5ft) high, facing the center of the detection area. Avoid thick walls/metal obstructions, which block mmWave signals. Maintain clear line of sight for both movement (6m) and presence (3.5m) detection zones.

### ⭐⭐⭐⭐⭐ Excellent Presence Sensor for Smart Homes

### ⭐⭐⭐⭐ Needs thread border router.
*by J***. on December 4, 2025*

Cannot be installed without a thread border router on your network, otherwise, it seems fine.

### ⭐ Doesn’t deliver on its promises
*by K***K on January 23, 2026*

I heard about this product a while back and was excited by the idea. Automate things to turn on when someone is in the room and off when they leave. Simple, right? That’s literally the entire promise. In reality, it behaves just like the Ecobee sensors it claims to improve on. Yes, it detects you, but then it seems to go into a long nap before checking again. Supposedly this thing polls far more frequently, and I even dug through the app to tweak every relevant setting. I lowered the unoccupied delay to the minimum of 20 seconds. I tried their AI “self-adaptation.” I enabled high performance mode. None of it made the slightest difference. I’ve been out of the room for over 30 minutes and the app still insists someone is present. Either my house is haunted or this product just does not work. Bonus frustration: after a shower, my robot vacuum was running and I noticed the wall mount had somehow ended up stuck to my bath rug, several rooms away from where the sensor was installed. The mount design is so poor it simply fell off the wall and onto the carpet. Save your money. I genuinely don’t know who is buying these and finding them satisfactory. My guess is this will earn a “frequently returned” label sooner rather than later.
